4 Claims.

This invention relates to frames for lamp shades, and more specifically to the stud support for the same and still more particularly to a stud support which swivels on a wire frame or harp.

Known to me is the production of lamp shade frames or harps having a swiveling support for the stud to which the lamp shade is attached by a finial and involving a wire frame to which a lamp shade stud is affixed by a stud supporting head. In such construction the stud head end may be resorted to, to exert frictional contact upon the wire in opposition to a head supporting the same. The relationship of the material of the head to the wire and the ability to alter the tension by the screw threading of the stud frequently results in such loss of a predetermined frictional contact as gradually to destroy the usefulness of the stud mounting to provide a swiveling movement between the stud and the wire frame.

Accordingly, it is an object of my invention to provide a lamp shade frame having a round or trunnioning section to which a stud support may be attached by a head, the head having provision for supporting the stud independently of any friction which the head may exert upon the frame. In this manner, the material of the stud, its head or any portion thereof, and the use of the screw shank thereof will not subject the head and the frame engaging segments to alteration. Thus, long life for swiveling frictional engagement is assured and is effected with great economy in production of the associated parts.

Still more particularly it is an object of my invention to provide a lamp shade frame having a stud supported thereon for swiveling movement relatively to the frame by the provision of a stud supporting head of extremely simple form and low cost construction, which independently of the stud support or any part thereof may be adjusted in affixing the same to the wire, to provide in an extremely compact bearing section, inherent resiliency and surface contact for swiveling movement of the head with relation to the frame. I

Still more particularly it is an object of this invention to provide a stud support characterized by a head having an undulating bearing surface in relation to which the opposed bearing head, walls, fingers, claws are stressed, to provide frictional engagement independently of the stud, whereby use of the finial on the stud in no way alters the frictional engagement and the material of the stud may be selected at random as well as to effect simplicity of assembly.

To attain these objects and such further objects as may appear herein or be hereinafter pointed out, I make reference to the accompanytoured 'to receive the hexagonal head ing drawings, forming a part hereof, in which- Figure 1 is a side elevation, partly in section, of a lamp showing my construction;

Figure 2 is a magnified fragmentary plan view of a stud supporting head on the line 2--2 of Figure 1;

Figure 3 is a view similar to Figure 2, showing the lower side of the stud supporting head;

Figure 4 is an end elevation thereof;

Figure 5 is a section taken on the line 5-5 of Figure 4;

Figure 6 is a fragmentary plan view of another embodiment of my invention similar to Figure 2;

Figure '7 is a fragmentary section taken on the line l---'! of Figure 6;

Figure 8 is a fragmentary section taken on the line 6-8 of Figure 7.

Summarizing my invention, it involves the provision in a lamp construction having a wire frame harp or the like in which a round section supports a head providing a mount for a finial stud characterized by a head formed with undulating bearing surfaces, which surfaces are in opposed relation to the wire engaging segment of the head in the form of integral ears, fingers, clamping members, claws, whereby the clamping members in the form as described are stressed in relation to the bearing members by the inherency of the bearing head and independently of the stud or any portion thereof, such as the head or shank.

Making reference to the drawing, I show a lamp [0 having a bulb socket H from which a frame 12 is supported. The frame l2 spans a light bulb l3 positioned in the socket II. The socket has a base M in which the fingers 15 of the frame are supported, either permanently or releasably. The frame I2 is preferably of wire having branches l6 and Il outlining a segment [8. Where round stock wire is employed, the segment 18 provides a trunnion. Where the wire is made of fiat stock, the segment 18 may be rounded, for purposes which will appear more clearly as this description proceeds.

In accordance with my invention, it is intended to provide for the lampshade frame l9 having the usual collar 26, a finial 2| for engagement of a stud 22. For this purpose I provide a stud supporting head 23. a disk-shaped sheet of malleable metal having an axially shouldered portion 24 perforated at 25 to receive the shank 26 of the stud 22. The head is pressed into a transverse undulating contour having a shouldered portion 21 and a seat 28, to receive the head 29 of the stud. Preferably the seat 28 is hexagonally con- 29. The head, which is spaced from the seat 28, is

The head comprises undulated transversely to provide an embossed ridge 30, concentric with axis of transverse semicircular contour, and preferably axially positioned with regard to the perforation 25, as out- 4 or springy materials to secure the necessary frictional contact.

Itwill be understood that the inherent benefits of my construction which I enumerate are exlined by he annular f r ove 3!, disposing 5 planatory and that other inherent advantages arms 32 and 33 to each side of the ridge. The arms 32 and 33 terminate in ears 34 and 35. The ears 34 and' j3fi manna-integral 01., each} constituted of branches-fiend 3'1 having--hookportions 38 and 39, terminating in edges 40 which may be brought in abutting position and outline -av bearing slot 4|, in which the edge QLis sufiLi ientIyi elongated to transfer the stress or tension of the bearing surfaces 38 and 39 againstltheawire: ii to the ridge 30, without interference It is contemplated by me to bias the ears 34 and 35 from the short side arms 32 andtu aboilti the ridges 30 as a bearing surface or fulcrum on n -trun n}- 110i h hifi e esiliencain; metrictignalfit and contactwhichthe, bearing;silrifaces a 38 and 39 makeina pposed stressed relation rto the ridges 0. pq he:t unnion-ma tian ofathe framegl 8;.
